Glioma is difficult to treat due to the unique tumor microenvironment and blood-brain barrier. (13aS)-3-Hydroxyl-6,7-dimethoxyphenanthro[9,10-b] indolizidine (PF403), a phenanthroindolizidine alkaloid, has been identified as a promising therapeutic agent for the treatment of glioma. However, the anti-glioma mechanism of PF403 in vivo has not been conclusively verified and must be further elucidated. Hence, a strategy without chemical modification was applied to identify the target of PF403. In this study, we identified nicotinamide phosphoribosyl transferase (NAMPT) as the target of PF403 by using thermal proteome profiling (TPP). Moreover, microscale thermophoresis (MST), surface plasmon resonance (SPR), and isothermal titration calorimetry (ITC) experiments confirmed that NAMPT exhibits good affinity for PF403. Direct and indirect enzyme activity assays revealed that PF403 inhibited the catalytic activity of NAMPT, leading to a decrease in the concentration of nicotinamide adenine dinucleotide (NAD⁺) in U87 cells. X-ray diffraction and amino acid spot mutation experiments revealed that PF403 primarily relies on the formation of pi-pi interactions with residue Tyr188 to maintain binding with NAMPT (PDB code 8Y55). After NAMPT was knocked down with lentivirus, PF403 lost or partially lost its antitumor activity at the cellular and animal levels. These findings suggest that PF403 exerts antitumor activity by directly targeting NAMPT.

Objectives:To explore the therapeutic efficacy of balloon stent kissing technique(BSKT)and jailing wire technique(JWT)in patients with true bifurcation lesions of the left anterior descending branch-diagonal branch of the coronary artery,and to observe the impact of these two interventional procedures on the lumen area,angina symptoms,cardiac function,myocardial injury,and myocardial perfusion of patients.Methods:A retrospective analysis was conducted in 203 patients with true bifurcation lesions of the left anterior descending branch-diagonal branch who underwent BSKT and JWT procedures and completed a 6-month follow-up in the Department of Cardiovascular Medicine at Shijiazhuang People's Hospital from January 2022 to January 2024.Patients were randomly assigned to the BSKT group(n=107)or the JWT group(n=96).The safety,efficacy,and myocardial perfusion indicators of the two groups were compared.Results:The minimum lumen area measured by intravascular ultrasound immediately after procedure,the Canadian Cardiovascular Society angina classification at 6 months post-intervention,the total score of resting+stress myocardial perfusion at 6 months post-intervention,the total number of segments with resting+stress myocardial ischemia,and the abnormal myocardial perfusion area in both the BSKT group and JWT group were significantly improved compared to baseline values(all P<0.05).In the BSKT group,87 cases(81.3%)achieved immediate success in stent placement,whereas in the JWT group,64 cases(66.7%)achieved immediate success in stent placement.The BSKT group significantly outperformed the JWT group.In terms of the myocardial injury and cardiac function indicators assessed on postoperative day 1,the cardiac troponin I level([0.22±0.13]ng/ml vs.[0.45±0.27]ng/ml,P<0.001),creatine kinase MB([35.24±13.15]U/L vs.[42.39±21.66]U/L,P=0.004),and B-type natriuretic peptide([133.52±25.62]pg/ml vs.[167.22±22.04]pg/ml,P<0.001)were all significantly lower in the BSKT group than in the JWT group.In terms of the myocardial perfusion indicators at 6 months post-intervention,the number of ischemic segments under stress(3.23±1.54 vs.3.87±1.62,P=0.004),the total score of stress perfusion(4.18±2.21 vs.4.97±2.96,P=0.031),and the abnormal myocardial perfusion area([7.04±3.27]%vs.[8.24±3.69]%,P=0.014)were all significantly lower in the BSKT group than in the JWT group.Conclusions:Both BSKT and JWT procedures can significantly improve the lumen area of the left anterior descending branch,angina symptoms,and myocardial perfusion in patients with true bifurcation lesions of the left anterior descending branch-diagonal branch.The BSKT procedure provides more adequate protection for the bifurcation vessels compared to the JWT procedure.

Objective To investigate the efficacy of preprocedural intracoronary injections of adenosine and sodium nitroprusside in patients with intravascular ultrasound-attenuated plaques(AP).Methods In total,200 patients with AP detected using intravascular ultrasound(IVUS)at Shijiazhuang People's Hospital from January 1,2022,to January 1,2024,were selected and randomly divided into conventional treatment and pretreatment groups,with 100 patients in each group.The conventional treatment group underwent standard percutaneous coronary intervention(PCI)procedures,whereas the pretreatment group underwent intracoronary injection of sodium nitro-prusside and adenosine through a guiding catheter prior to PCI.The observation parameters included intraoperative no-reflow(NR)inci-dence,post-PCI TIMI myocardial perfusion frame count(TMPFC),perioperative myocardial infarction(PMN),and 6-month major adverse cardiac and cerebrovascular events(MACCE).Results The pretreatment group exhibited a significantly lower intraoperative NR inci-dence,reduced postoperative TMPFC,and attenuated PMN severity than the conventional treatment group(P＜0.05).Conclusion Pre-procedural intracoronary administration of adenosine and sodium nitroprusside through a guiding catheter can effectively reduce PCI-re-lated NR occurrence,improve post-PCI TMPFC,and mitigate PMN in patients with AP,although no significant improvement in MACCE incidence can be observed at the 6-month follow-up.

Objective To analyze the mediation effect of self-efficacy and mental toughness between self-management behavior and postoperative rehabilitation in patients with cervical spondylotic radiculopathy.Methods A total of 180 patients with cervical spondylotic radiculopathy diagnosed and treated in the First Hospital ofNanchang from April 2022 to April 2024 were selected by convenience sampling method.The patients were investigated by general data questionnaire,Connor-Davidson resilience scale(CD-RISC),chronic disease self-efficacy scale(CDES),rehabilitation evaluation scale for cervical spondylotic radiculopathy(RES-CSR)and chronic disease self-management scale(CDSMS).Results The scores of CD-RISC,RES-CSR,CDES and CDSMS were(64.41±10.12)points,(78.84±12.07)points,(41.26±3.18)points and(53.14±6.38)points respectively.The results of correlation analysis showed that postoperative rehabilitation was significantly positively correlated with mental toughness,self-efficacy and self-management,self-management was significantly positively correlated with mental toughness and self-efficacy,mental toughness was significantly positively correlated with self-efficacy(P＜0.05).Mental toughness and self-efficacy played a mediating role in the relationship between self-management and postoperative rehabilitation of patients with cervical spondylotic radiculopathy,and the mediating effect value was 0.270 and 0.136.The two continuous paths had a chain mediating effect,and the mediating effect value was 0.150,accounting for 18.70％,9.42％and 10.39％of the total effect value,respectively.Conclusion The self-management behavior of patients with cervical spondylotic radiculopathy has an important impact on their postoperative rehabilitation,in which mental toughness and self-efficacy play a chain intermediary role.Nursing intervention can enhance the self-management behavior and mental toughness of patients with cervical spondylotic radiculopathy and improve their self-efficacy,so as to improve their postoperative rehabilitation level.

ObjectiveTo explore the clinical efficacy and safety of Fuzheng Huaji Longbi decoction in treating benign prostatic hyperplasia （BPH） in the patients with the syndrome of healthy Qi deficiency and blood stasis. MethodA total of 94 BPH patients were randomized into control and observation groups， with 47 patients in each group. The control group was treated with doxazosin mesylate sustained-release tablets， and the observation group with Fuzheng Huaji Longbi decoction on the basis of the therapy in the control group. After eight weeks， the international prostate symptom score （IPSS）， quality of life （QOL） score， residual urine volume （RUV）， maximum urinary flow rate （Q_max）， TCM syndrome score， TCM symptom score， electrocardiogram， and liver and kidney function were determined to evaluate the clinical efficacy and safety of the two groups. ResultAfter 8 weeks of treatment， the total response rate in the control group was 63.64% （28/44）， which was lower than that （84.44%， 38/45） in the observation group （χ²=5.026， P<0.05）. The clinical efficacy in the observation group was higher than that in the control group （Z=-2.17， P=0.030）. The treatment in both groups decreased the IPSS， QOL score， RUV， and TCM syndrome scores and increased the Q_max （P<0.05）. Moreover， the observation group had lower IPSS， QOL score， RUV， and TCM syndrome score （P<0.05） and higher Q_max than the control group after treatment （P<0.05）. The treatment in the observation group decreased all the TCM symptom scores （P<0.05）， while that in the control group only decreased the frequency of urination at night and the scores of dysuria， weak urine stream， and post-urinary drainage （P<0.05）. After treatment， the observation group had lower frequency of urination at night and lower scores of mental fatigue， cold limbs， lower abdominal discomfort， and loose stool than the control group （P<0.05）. No adverse events associated with the administration of Fuzheng Huaji Longbi decoction were observed during the treatment period. ConclusionFuzheng Huaji Longbi decoction is effective in treating BPH in the patients with the syndrome of healthy qi deficiency and blood stasis. It can relieve the clinical symptoms and improve the quality of life， being a safe and reliable choice for clinical application.

Objective: To investigate the smoking cessation intention and attempt to quit smoking among smokers at ages of 15 years and older in a district of Beijing Municipality, so as to provide insights into formulation of tobacco control interventions. Methods: Permanent residents at ages of 15 years and older were sampled using a multi-stage stratified cluster sampling method from a district in Beijing Municipality, and all smokers were recruited. Participants' demographic features, tobacco use, intention to quit smoking, attempts to quit smoking and awareness of tobacco-related hazards were collected using the Beijing Adult Tobacco Survey. The intention and attempts to quit smoking were analyzed among smokers, and factors affecting the attempt to quit smoking were identified using a multivariable logistic regression model. Results: A total of 687 smokers were surveyed, including 669 men (97.38%), 497 from rural areas (72.34%), 351 daily smokers (51.09%), 336 occasional smokers (48.91%), 329 with intention to quit smoking (47.89%), and 178 with attempts to quit smoking during the past one year (25.91%). Univariable analysis showed that area, age, educational level, smoking status, tobacco health literacy and tobacco control information acquired from media were factors affecting intention and attempts to quit smoking among smokers (P<0.05). Multivariable logistic regression analysis showed that smokers with intention to quit smoking (OR=5.444, 95%CI: 3.585-8.268) and occasional smoking (OR=2.142, 95%CI: 1.312-3.497) were more likely to attempt to quit smoking. Conclusions Approximately half of smokers have intention to quit smoking in a district of Beijing Municipality; however, the percentage of attempts to quit smoking is low. Targeted interventions are required for smokers with different characteristics to improve the intention to quit smoking and promote smoking-quitting behaviors.

The cardiovascular patch, served as artificial graft materials to replace heart or vascular tissue defect, is still playing a key role in cardiovascular surgeries. The defects of traditional cardiovascular patch materials may determine its unsatisfactory long-term effect or fatal complications after surgery. Recent studies on many new materials (such as tissue engineered materials, three-dimensional printed materials, etc) are being developed. Patch materials have been widely used in clinical procedures of cardiovascular surgeries such as angioplasty, cardiac atrioventricular wall or atrioventricular septum repair, and valve replacement. The clinical demand for better cardiovascular patch materials is still urgent. However, the cardiovascular patch materials need to adapt to normal coagulation mechanism and durability, promote short-term endothelialization after surgery, and inhibit long-term postoperative intimal hyperplasia, its research and development process is relatively complicated. Understanding the characteristics of various cardiovascular patch materials and their application in cardiovascular surgeries is important for the selection of new clinical surgical materials and the development of cardiovascular patch materials.
